[0065] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0066] Reference Figure 1-6 The casting mold 100 with burr removal function includes: a lower mold cover 101, an upper mold cover 102, a first ejector rod 103, a second ejector rod 104, and a driving device 105; the lower mold cover 101 has a first shaping groove 101a; the upper mold cover 102 is arranged on the lower mold cover 101, and has a second shaping groove 102a on the upper mold cover 102. When the upper mold cover 102 is fixed to the lower mold cover 101, the first shaping groove 101a is connected with the second shaping groove 102a to form a mold groove 101b, and the inner space of the mold groove 101b is rotationally symmetrical. And the rotation axis 105b line of the mold groove 101b is located on the lower mold cover 101; openings 101c are opened at both ends of the lower mold cover 101, and the openings 101c are circular holes, which are connected to the first molding groove 101a, and the axis of the opening 101c is coaxial with the axis of the mold groove 101b; the first push rod 103 is rotatably arranged in the opening 101c at one end; the second push rod 104 is rotatably arranged in the opening 101c at the other end; the driving device 105 is arranged on the lower mold cover 101, located at the first push rod 103, and is used to drive the first push rod 103 to rotate and swing.

[0067] During the casting process, when the cast product is in a state of being quickly formed, the driving device 105 is started, driving the first push rod 103 to rotate. The first push rod 103 presses against one end of the product, driving the product to rotate and swing. The second push rod 104 presses against the other end of the product. When the product rotates and swings, the burrs formed on the product at the connection between the first molding groove 101a and the second molding groove 102a are pulled and smoothed.

[0068] An air inlet hole 101d connected to the opening 101c is provided at both ends of the lower mold cover 101, and the air inlet hole 101d is connected to the air pump; a first spring 106 is provided on the end away from the second push rod 104, and the first spring 106 is located between the first push rod 103 and the air inlet hole 101d.

[0069] A cooling ring groove 101e is provided at the lower end of the lower mold cover 101. The cooling ring groove 101e is filled with coolant and surrounds the lower portion of the first molding groove 101a.

[0070] The driving device 105 includes: a liquid inlet channel 105a, a rotating shaft 105b, a blade 105c, and a transmission group 105d; the liquid inlet channel 105a is located at the first push rod 103 on the lower mold cover 101 and is connected to the cooling ring; the rotating shaft 105b is rotatably arranged on the lower mold cover 101, and the rotating shaft 105b is partially located in the liquid inlet channel 105a; the blade 105c is arranged at one end of the rotating shaft 105b, and is located in the liquid inlet channel 105a; the transmission group 105d is arranged on the lower mold cover 101.

[0071] The first push rod 103 is initially slightly retracted into the opening 101c. When the product is to be driven to rotate and swing, the air pump is started, and the air in the air inlet 101d and the opening 101c form high-pressure gas, pushing the first push rod 103 to move toward the second push rod 104, so that the first push rod 103 rests against the end face of one end of the product.

[0072] When the coolant enters the liquid inlet channel 105a, the flow of the coolant drives the blades 105c to rotate, and the blades 105c drive the rotating shaft 105b to rotate, and through the transmission of the transmission group 105d, drive the first push rod 103 to rotate.

[0073] The transmission group 105d includes: a cam 105e, a guide rod 105f, a slide plate 105g, a rack 105h, meshing teeth 105i, and a second spring 105j; the cam 105e is fixed on the end of the rotating shaft 105b away from the blade 105c; the guide rod 105f is vertically fixed on the lower mold cover 101 and is located on one side of the first push rod 103; the slide plate 105g is slid up and down on the guide rod 105f; the rack 105h is vertically fixed on the slide plate 105g, and the rack 105h is located on one side of the first push rod 103; the rack 105h is fixed on the first push rod 103 and meshes with the rack 105h; the two ends of the second spring 105j are respectively fixed on the slide plate 105g and the lower mold cover 101, and the second spring 105j is located at the upper end of the slide plate 105g, which is used to push the slide plate 105g to move downward.

[0074] After the rotating shaft 105b rotates, it drives the cam 105e to rotate. The cam 105e lifts the slide plate 105g, driving the slide plate 105g to move upward. During the rotation of the cam 105e, the second gear will force the slide plate 105g to move downward, and finally the slide plate 105g and the rack 105h will move back and forth up and down. The up and down movement of the rack 105h, under the action of the meshing teeth 105i, drives the first push rod 103 to rotate and swing, so that the product rotates and swings back and forth in a small amplitude, so that the burrs of the product can be quickly and repeatedly scraped flat in a short time.

[0075] The first push rod 103 includes: a connecting portion 103a, a meshing portion 103b, and a butting portion 103c; the connecting portion 103a is slidably arranged in the opening 101c; the meshing portion 103b is integrally formed on the connecting portion 103a; the butting portion 103c is integrally formed on the meshing portion 103b at an end away from the connecting portion 103a; the connecting portion 103a, the meshing portion 103b and the butting portion 103c are all constructed in the form of a cylinder, the diameter of the meshing portion 103b is smaller than that of the connecting portion 103a and the butting portion 103c, the meshing teeth 105i are located on the side of the meshing portion 103b close to the connecting portion 103a, and surround the meshing portion 103b; a buffer sheet 107 is provided on the end of the butting portion 103c away from the meshing portion 103b.

[0076] When the air pump is turned off, the first spring 106 pulls the connecting part 103a to retract. At this time, the meshing tooth 105i is separated from the rack 105h. Even if the rack 105h moves up and down, it will not drive the meshing part 103b and the abutment part 103c to rotate and swing back and forth. Only when the air pump is turned on and the high air pressure is greater than the elastic force of the first spring 106, the meshing part 103b will be pushed to allow the meshing tooth 105i to mesh with the rack 105h. At this time, the abutment part 103c will be driven by the rack 105h to rotate and swing back and forth.

[0077] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of application involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above application concept.
